General Culture:
Tender perennial that is winter hardy to USDA Zones 8-11. In St. Louis, it is typically grown as an annual. It is best grown in moderately fertile, organically rich, consistently moist, well-drained soils in full sun. Seed may be sown directly in the garden 1-2 weeks before last frost date or started indoors 6-8 weeks earlier. Pinch stems of young plants to promote bushiness. Deadhead spent flowers to prolong bloom. Plants sometime struggle in hot summer climates such as St. Louis, and may temporarily stop blooming in the heat of the summer. When flowering declines, shear planting to promote a fall bloom.
Noteworthy Characteristics:
Twinspur is a mat-forming plant that typically grows to 12?tall and spreads to 18?wide. Features loose terminal racemes of pink flowers (3/4?across) with yellow throat spots and two downward-angled spurs. Flowers appear above the foliage from summer into fall on stems rising 6-12?tall. Ovate toothed glossy green leaves (to 1?long).
Problems:
No serious insect or disease problems. Watch for snails and slugs.
Uses:
Borders, rock gardens, pots/containers, hanging baskets.
